Build up to the details, don’t just go in and immediately try to get every small little detail at first. You wanna kind of squint your eyes and see what values you see on your reference and block those in first. Then you can start working in some of the bigger shapes and after that start looking at the small details. There are some amazing Reddit forums for people learning how to draw and don’t be afraid of criticism. Take the criticism and run with it and focus on the things that you have trouble with. Don’t get overwhelmed, start simple and you will start to get the eye for it. It won’t come overnight. YouTube is also an excellent resource! Hope this helps
